MAGNETO-ELECTRIC GENERATOR.

\ Application ied September 8, 1908. Serial No. 451,992.

To all whom 'it may concern.'

Beit known thatl we, CHESTER A. STONE .-and. GrARNE'r C.JBROWN, 'citizens of the United States, and residents'of the city of Buffalo, inthe county of Erie and State of New York, have invented or discovered'certain'new and useful Improvements in Magneto-Electric Generators,'of which the following is a specification.

The object of our-invention is to provide a magneto electric generator capable of producing powerful jump sparks for igniting 4the explosive mixtures ina hydrocarbon en` gine or for lother Ysimilar purposes; to pro vide improved means of construction whereby the current generated bythev armature is conducted directly to the distributer with i 'out passing through bearing partsl and thereby rendering the same 'simple and certain in action; and in the novel features of construction and combination/of parts here- .-inafter set forth.

In the accompanyingvdrawings, Figure 1 is asectional elevation through the center of the generator. Fig. 2 is an end elevatioof the'generator with the distributer and circuit breaker covers removed. Fig. 3 is a section through the distributer and collector Vad ring on the line A B of Fig. 1.

In the drawings, 1 indio tes an armature having a primary and a s condary winding inthe ordinary manner for generatinga low and a high tension current when revolved in the magnetic field produced by the permanent horseshoe magnets 2, 2, 2. A circuit breaker which consists of an arm 3 pivoted at 36 and carrying a roller 37 and having .a Contact point 38 keeps the circuit of the lprimary current closed when in touch with the y so Vdoing separates the points '38 and 39.

22 is a rod which holds the primary curi rent collector 18 and cam 21 in position and lector 15, then through the collector brush 5, distributer ring 41, distributer brushes 12 and 42, which are mounted in the distributer arm 11 and connected by conductor 13, then through the various contacts 6, 6, 6, 6, and contact plugs 34,34, 34, 34 to the sparking plug of a motor.

7 is a block of insulating material mounted on one end of the generator and above the collector ring 16 through which the high tension current is conducted by means of the brush 5, distributer ring 41, contact 6, 6, 6, 6 and plugs 34, 34, 34, 34 which are embedded in it.

A 43 is a cover to inclose the distributer arm 11 and 24 a cover to inclose the circuit .breaker mechanism.

8, 8 are gears'for conveying motion from I the armature shaft to the distributershaft 9. i

10, 1() are the distributer shaft bearings.

14, 14 are the armature shaft bearings.

The operation of the generator is as follows: The armature 1 is first made to revolve by means of the driving shaft 27 and in the magnetic field produced by the permanent horse-shoe magnets 2, 2, 2 when at each one-half revolution the magnetic lines of force generate a current yin the primary or low' tension circuit which increases in strength until the polarity of the magnetic ield begins to change. At this moment the circuit of the primary winding is broken by the cam 21 lifting the arm 3 and separating the'contact points 38 and 39, when a secondary or high tension current is induced in they secondary winding of the armature by the rapid demagnetization of the iron core of the armature. The rapidity of this demagnetization is increased by the condenser 4. The secondary or high tension current induced in the secondary winding is collected by means of the ring 16 and conveyed successively to the various contact plugs 34, 34, 34, 34 by means of the dis-l tributer varm 1l which -is rotated by the gears 8, 8, and' then to the spark plug of a motor.

Ve do not restrict ourselves to the precise construction of the details herein shown, butl various changes may be resorted to within the 'scope of; our claims hereinafterv contained.

' said armature, a collector ring mounted on the shaft of said armature opposite toits driven end, la distribnter ring mounted on said distributer shaft in juxtaposition to said collector ring and elasticallyv connected therewith by means of'a collector brush.

mesme 2. ln a magneto electric generator: 'the combination, of an armature having a pri mary and. a secondary coil wound thereon, a sparking device in the circuitA of the secondary coil and means to collect and distribute the current from said secondary coil to said sparking device,v said meansconsist` ing of a coliector ring mounted on', and-in sulated from, the shaft of said armature, 8 collector brush connecting said collector ring with a distributer ring, contacts located around said distributer ring, .distributerbrushes in a dist'ributer arm and Contact plugs connected with said contacts, said collector' brush.. distributer ring, contacts and Contact plugs located in one piece of insulating material in'juxt'aposition to said collec-toc ring', substantially as set forth.
